INHALER.

SIPECIFIGATION forming part of Letters Patent No. 780,421, dated January 17, 1905.

i Application filed November 10, 1903. Serial 110.180,538.

sprayed liquid is evaporated by means of the increasing temperature of the steam, while the steam is simultaneously condensed.'` The evaporation of medicaments to be inhaled is necessary, as gases can penetrate into any part of the lungs, while this is only partially possible for sprayedliquids.

The construction of the apparatus is based on the theorem that sprayed liquids evaporate much easier and quicker than liquids in ordinary condition.

In the accompanying drawings the apparatus is shown in Figure 1 in a front view, partly in section.- Fig. 2 is a side View of the metal Fig. Bis aside view of the metal cylinder, which is sh'ownin Fig. 4L in a view from the bottom. Fig.'5 shows the regulating' device for the temperature, which is shown in Fig.'6 in aside View.

rlhe improved inhaler consists of a lyreshaped glass tube c, which has at the upper ends two horizontal arms a of larger diameter than the lyre-shaped glass tube c. Over the end of one of the horizontal arms aametal cylinder 1 is placed, in which terminate two spraying-pipes 3 11V, one forthe liquid and the other for the steam, which are arranged in the ywell-known manner so that their orifices stand at right angles, one abovetheother. A metal cap 2 is placed over the open end ot' the cylinder 1.

At the bottom of the lyre-shaped glass tube c, as well as at the bottom of the horizontal upper arms a of said tube, short nozzles 6 are provided, which are connected, by means of india-rubber hose, with athree-branched .evident and clear from Fig. 1.

In the walls of the metal cylinder 1 longitudinal slots 8 are provided, one at each side,

the width oi' which can be adjusted in any suitable manner, so as to regulate the quantity of air admitted into the apparatus. The adjusting device for said slots shown in the drawings consists of a ring 9, which isprovided with a scale to allow a very close regulation or' the quantity of air, and during the rotary movement of ring 9 on tubel said ring is shifted by means or' a small screw in the flange thereof catching into groove 10 in the cylinderl, and it opens or closes thereby the slots 8 in part 1, a fact which becomes at once Said regulating-ring stands vertically on the cylinder.

The apparatus operates as follows: The jet 'of liquid medicaments Hows into the metal cylinder through the horizontal pipe 3 and the liquid is sprayed bythe jet of steam, which strikes it at right angles coming out of the vertical pipe 4. The mixture of sprayed liquid and steam now passesthroughl the metal cylinder 1, where it is mixed with air entermixture oi' steam and sprayed liquid through the lyre-shaped glass tube c the liquid is completely evaporated, the lyre-shaped glass tube acting' asA thermo-accumulator. The smaller the diameter of the lyre-shaped glass tube is chosen the greater is the increase in temperature. The evaporated medicament is inhaled from the end m of the other arm, or' the.

lyre-shaped glass tube 0. The water of condensation flows off through the three nozzles 6 at the bottom of the horizontal arms a and at the bottom of the lyre-shaped glass tube c into pipe 7.

Having fully described my invention, what I claim, and'desire tosecure by Letters Patent, is-

An improved inhaler comprising in combination a lyre-shaped glass tube, two horizon- IOO tal arms at the upper end oi' the lyre-shaped glass tube of larger diameter than the same, studs at the bottom of the horizontal arms and of the lyre-shaped glass tubes, a threebranched pipe Jfor the outliow'oil the condensed Water, india-rubber hose connecting the studs with said three-branched pipe, a metal cylinder at the end of one of the horizontal arms, a metal cap Closing the open end of said cylinder, a horizontal pipe for the supply of liquid and a Vertical pipe for the supply 0f a steam-jet terminating in said metal cap, longitudinal slots in the metal cylinder, a vertical ring with a scale on its surface screwed With a liange on the metal cylinder so as to more or less cover the longitudinal slots, substantially as described and shown and for the purpose set Jforth.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
